carnation succulent plantlet--a stable teratological growth

Axillary buds of carnation (cv. Cerise Royalette) cultured in vitro, frequently became ‘succulent’ plantlets, which proved to be a teratalogical stable type of growth. Agar concentration (0.8–1.2 per cent) in the medium influenced the type of development, and 0.05, 1 or 2 mg l−1 of NAA in the medium...

Description
Summary:Axillary buds of carnation (cv. Cerise Royalette) cultured in vitro, frequently became ‘succulent’ plantlets, which proved to be a teratalogical stable type of growth. Agar concentration (0.8–1.2 per cent) in the medium influenced the type of development, and 0.05, 1 or 2 mg l−1 of NAA in the medium did not change the results. The succulent plantlets did not revert to normal growth when transferred to medium containing more agar, which favoured normal plantlet development. Succulent excised meristems developed mainly into succulent plantlets. A hypothesis is made that a rearrangement of the meristem occurs in the first days of growth, the consequence of which is the succulent plantlet, which is no longer influenced by agar concentration in the medium.
